I have an HP ML350 with two 1TB Hot Plug SATA hard drives. It's running Windows Server 2008R2 with a software RAID 1 and Disc 0 has failed. It will randomly allow me to boot to the bad drive, but only stays online for about 5 minutes and shuts down. This is the only customer I have who uses software RAID instead of hardware RAID, so I'm not familiar with it's functionality. I have a new identical replacement 1TB hard drive, but would like some guidance for replacing this before I go onsite. Could someone give me step by step instructions?
